Newcastle was a 44-gun fourth-rate frigate of the English Royal Navy, originally built for the Commonwealth of England by Phineas Pett the Younger at Ratcliffe, and launched in May 1653.

This action resulted in the destruction of the entire pirate fleet, which won the Newcastle lineage its first battle honour.

In 1657 she took part in Admiral Blake's daring attack on Santa Cruz de Tenerife, and in 1665, she fought at the Battle of Lowestoft.

On 14 March 1674,[2] Newcastle, under the command of Sir John Wetwang, captured the Dutch East India ship Wapen van Rotterdam in the Battle of Ronas Voe.

Shortly before Plymouth declared for William III on 18 November, Churchill entered the port for repairs but this appears to have been an excuse; Newcastle was the first significant naval defection and the rest of the fleet soon followed.
